ln the. exeniplicalion of our invent-ion, as disclosed in the firstJrhiee figures of the fliawings", the appara-ius comprises the main bodyoi'f'ank 2Oq preferably made cylindrical in shape and of suitablematerial, such as sheet metal.; the tank being divided into separatecompartments ai'i'anged one above los the other; the upper compartmentbeing provided with an insulating wall 21 so as to provide a suitablecooling chamber 22 adapted to be packed with ice; while the lowercompartment is adapted to provide a suitable storage chamber for anoriginal container' or bottle 24, is well as a drip and cupreceivingvessel 25.

In order to permit proper access to the storage chamber 23, the lowerwall of the suitable means for draining the chamber, as,

for example, the drip-pipe 29 arranged in the bottom of the upper orcooling chamber 22 and at a fpoint immediately above the drip-vessel 25;the drip-pipe 29 being preferably in the nature ot a spigot, as shown,so that passage of air into the coolingV chamber will ordinarily beprevented.

,The cooling chamber 22 is provided with a liquid-receiving member orvessel 30, preferably made of vitreous ware, and given any desired shapeor. configuration, which will permit it to be inserted into the coolingchamber and at the same time provide sufficient. ice-receiving space, asdisclosed in Fig.

1. `We prefer to form the water-1eceiving vessel or member 30 with thetwo compartments or portions 31 and 32, see Fig. 3, having communicationwith each other at the lower end thereof, to wit,I beneath theintermediate or separating wall 33, see Fig. l. The portion 32 isadapted to extend some' what beyond the upper portion of the vessel 3()so as to permit it to pass through a suitable opening in the top memberor cover 34 or'4 the apparatus; the extended neck of the portion 32being preferably provided with a flared orifice to receive the neck ofthe inverted original container or` bottle 24, as shown in Fig. 1. Weprefer to provide the flared orifice of the portion 32 with a resilientor rubber ring 35 Vto provide a proper cushion for the container orbottle 24, and

' at the same time provide a substantially airiight connection.

The portion 31, of the liquid-receiving receptacle 30, is provided withthe forwardly presented outlet portion 36, preferably formed integralwith the upper portion thereof. The portion. flis provided with adischarge spout :3T which is preferably detachably Secured inv theopening 38 in the lower part of the extension 3G, see Figs. 1 and 2. Theportion 3l. within the extension 3G, is provided with an opening 3). seeltig. 2; and the walls on both sides oi. the. opening 39 are providedwith the lugs 40. The lugs 40 are notched to provide a suitable bearingfor the trunnions 41 formed integral with, or otherwise secured to, thespout 42 of the dipper or cup-member 43, thereby holding the member 43in place and free to oscillate in the lugs or brackets 40; the cup ordip-member 43 being located within the portion 31 of the receptacle 30,while its spout 42 extends through opening 39 and into extension 36, asshown in Fig. 1. a

The spout 42 is shown provided with the upwardly presented extension orlug 44 which is provided with the elongated slot 45, adapted to receivea pin 46 on the lower end of an arm 47 of the coin-controlled mechanism.The cup or dipper-member 43 has the upwardly presented wall 48 at theforward portion thereof in order to prevent the liquid from spilling outover the top of thev member when it is tilted into the emptying ordischarging position shown in full lines in Fig. 1; the dripping orintake-posi tion of the member 43 being shown in dotted lines in saidiigure.

' As the bottle or container 24 is provided with an extension or tube 49which extends into a plane slightly beneath the horizontal planeoccupied by the bottom wall 50 of the extension or portion 36, it isevident that the liquid in the receptacle 30 will form a seal for thebottle or container 24 as soon as the liquid vin the receptacle lrises'to a height where the orifice of the extension or tube 49 will becovered or immersed and thereby prevent a'ir from entering the containeror bottle 24. The top member or cover 34 of the cool ing chamber isprovided with a cup-holder and vcndin(T device inclosed by the innercasing 51.

provided with a partial bottom 52, see Fig. 11, terminatingat theforward end of the receptacle in the narrow flanges 53, 53 arrangedalong the side walls of the receptacle, as shoyvn in Fig. 10. Thepartial bottom 52 and the side flanges 53 provide support for thesuperimposed sanitary paper cups 54, shown in section in Figs. 10 andll, and in full lines in Fig? 15. The paper cups, however, need notnecessarily be of the particu. lar construction or type illustrated, butof any suitable construction that will permit them to be collapsed andclosely packed in the receptacle 51. The paper cups illustrated in thedrawings are in the nature of an openended envelop, with the short wallpresentled downwardly and the open end toward the rear oi' the casing,as shown in Fig. l1.

The front wall of the receptacle 51 is provided with a transverselydisposed opening or slot for the passage of the plunger 5o which isadapted to slide between the side flanges 53, as shown in Fig. 10. The

he casing 5l is preferably of ,the rectangular construction shown, andis t-ae'n head TT and 7S being of a size slightly smaller than thediameter of the rom the composite slot is adapted to reeeive when theheads are in normal or the close position shown in Figi. H. ,so that`when a proper eoin is inserted and pressed sullieientl'v downward. asshown in Fig. S? at the heads otA the levers 73 and T4 will be `torcedapart and oscillated on their respeetive pivotal points 75 and i't'i.turned to its normal position liv means of a suitable spring while lever7l is held and returned to its normal position by means et" the spring:S1.

Lever 73 is shown provided with a socket Si adapted to reeeive the lowerend of lever 74.- when the levers have heen oscillated into theseparated position by means of a coin. as shown in Fig. t): the lowerend of lever 7l normally being: adapted to engage with lever 78, asshown in Fig. 9. and thereby assist in maintaining the lower part oflever 73 in locking,r engagement with a raek 83 which is seein-ed to theslide or plunger 56; the rack S3 heineT seein-ed to slide or plunger 5G.hv means ot the hraeket Si show n in Fig.' 10, The. rack S?, therefore'of'erlaps the lower edge ot' the short side Wall ot' easing 5l. asshown in Figs. 8. 9 and 10. The rael .QZ-l is provided with an upwardlypresented arm H5. theupper end whereof has n shield or member .QG whichis adapted to pass across the tops of the heads 77 and`78 of the levers73 and 74. respectively. as indicated in Fig. 9. The shield. or member86 will not only force the coin or token downward sui'lieienth7 so as tocause it. to become disengaged with the heads 77 and 78 and dropped intothe coin-receptacle 87 located beneath the short side wall of the casing51. butI also prevent any possibility of the coin beinelr withdrawnafter the levers have. been sufficiently separated and the slide orplunger forced out.. vThe lower end of lever 73 is preferably shoulderedso as to engagewith the teeth of the rack S3. ln order to prevent thetoo far 'movement of 'the lower endet the lever, we provide the stop 88.In the normal position of the@ mechanism, the lower end of lever 7 3will be in engagement, with the first tooth of the rack 83, as shown indotted lines in Fig. 8, While complete operation of 'slide 'or plunger56 will bring the rear end of rack 83 into engagement with the lower endof lever 73. The rack is l. provided with a number of notches or teethwith which the lever 73 will form locking engagementy during itspartial. return to normal position.

B v reasonbf this construction. it is imporsilileior thel operator to somanipulate the slide or plunger 56, that the insertion of a single coinwould enable him to secure more than one. cup and dispense or obtainmore than one drink. With the, rack S3 pro lieier Til is held and re.

vided with a number ot' teeth or notches as shown. it is evident that apartial return otl the slide or plunger .'it, to normal position. willresult in the rack. and therefore also slide or plunger 5o, becominglocked against a reverse. or outward movement..

The notch or socket 5:, formed in lever 725, permits the properoseillation of lever 7l, namely out of locking engagement with leverT23, when a proper coin has been inserted. v

ln order to prevent. spring Si from d avv ingthe.\lower end of lever ilbevond its locking eontart with lever 725. we .rovide e. stop'e'i); andthe too iar separation of the heads 7tand in' otI the levers. by theiusertion of a slug or token' of improper diameter, is prevented h v thestop or lug Ut) with which thehead Th' contacts. while the front wallot' the easingl would prevent the head 7T from being forced beyondproper position'. basingr 5l and the mechanism mounted thereon. as wellas the coin-receiving; reeepta# ele $7. are all ineased b v an outercovering or easing Jl which is adapted to' be slid over the top ofcasing 5l and ItheI mechanism se cured thereto. The easing 91 is lockedin place by means ot' a suitable lock. indicated at J2-in Fig. l1;easingr 51 beingY perinanently secured to the top or eorer 3l of themain portion of the apparat-us.

The to i or cover at one side to the main body or ta-nlr of the.

i apparatus. while the other side may be, prorided'with a suitable loelrso that' access to the interior oi the. water-reeelvingr Cooling,ehamher eannot he had b v unauthorized individuals.

rThe top ot' the outer shell or easing 91 is- 'Figa ll, pivotall)ymounted aty the point 97.

This disk 96 is provided with a number of slots 9S adapted to be broughtinto register with the enlarged slot'V or openingl 93 in the outercasing' ttl and the comparatively large slot, or opening 9i in the topof the inner shell or easing 51. The openings or slots 93 and. 9i arelocated immediately above the slotted heads 77 and 78 of the levers 73and 74. shown in Fi 1 9. The slots 98 in the disk 9G are of di erentIsizes and also located at, different distances from the. center of thedisk, so thatone of the slots 98 maybe brought beneath the'large slot oropening", .inthe outer casing.r and in alinement with the selected slotin the, heads 't' 7 and 78 of the iovers'73 and 74. For example.' theslot. 9S, shown in Fig. il, beneath slotl 9?v of the :il is preferablyhinged.

outer shell creasing, is adapted to aline with ythe slots 7 9 adjacentthe sides oi' heads 7 7 and 78; so that -thevdevica as just described,will merely lpermit the insertion of a `coin of iven dimensions, as, forexample, a centw ile the other 'slot 98 1n disk 96,

when brought beneath the opening 93 of' the outer shell or casing, isadapted to register with an intermediate slot 7 9 in heads 77 and 78,thereby settin the devioe to receive a coin of diierent imensions as,for exanr ple, a five cent piece, rThe disk 96 maybe provided withadditional slots at a proper distance from the center commensnratewiththe width of heads 77 and 78, adapted to register with different sizedslots in the heads "7 7 and 7 8, so that the device will loe adapted.lock 92 into unlocking position 'oy the use of a proper key. Loch 92therefore not only v unlocks casing 9i from casing 5i, lout, 'by its'operation, is also put' into a position which will permit rotation ofdisk 96; access to thel disk 96 'only 'being had from the under side ofshell or casing. 91.

In order to direct the inserted coin into the coin-receptacle 87, afterthe coin has passed through the composite slot oi' the heads 77 and 78,the side wall of the inner shell or casing 51 is shown provided with asuitable guide 100, see Figs. 8 and 9, the

lower end whereof is curved slightly awafy on the front wall from theside wall or shell 5l, therelijg? directing the 'coins to the side of`the levers.

The outer shell or casing 9i may also he used asa means for holdingsuitable adver tisements or other inscription. 'We have shown the top ofshell or easing 93. provided with the upwardly presented frame portion101, formed so as to permit the insertion of a card, as at B, providedwith the desired advertisement or inscription. The card B is preferablyinserted within the trame 10i from the bottomv so as to prevent the iniproper removal thereof. lin order to permit access to frame 101, for thepurpose of serting or withdrawing the card B, we have shown the frame101 removably secured to the top wall of shell or casing '91 hy means ofthe butterfly nuts 102, see Fig. 10, which screw on the dependingscrew-rods 103 se cured to the frame-member 101 end. extending throughsuitable openings in the top Wall of outer shell or easing 2l.

In Fig. d, we show a inediti-ed 'forni of invention, in so iar as thecooling chamber is concerned, as well as a dierent method oi. mountingthe cup or dip-member. instead of 'providing the upper portion of thebody or tank 20 with an insulated wall. like that shown in Fig. l, theupper portion is adapted to receive a suitable receptacle or iceholdingvessel iOi, composed oi' suitable inaterial such as liber and the like,arranged not to interfere with the insulation-holding portion 34. of thecover 34.

The receptacle or vessel 1.04 is provided with a liquid-holding vessel30, preferably of vitreous ware, so made as to permit suticient. spacefor the insertion oi.' ice within the vessel 10d about thewater-receiving .vessel 30s.

The water-receiving vessel 30a is provided 'with an intermediate wall orpartition 105 which, with the rear wall of vessel 3G, is adapted toconstitute' the hott-le of: containerreceiving portion; the upper endsof the intermediate wall 105 and the rear wall being extended through anopening in the top 311i oi. the tank and suitably tiered to receive theinverted container or hottie The front Wall the vessel 30?, like thevessel shown in Fig. 2, is proridedwith a suitable extension 36a toreceive the liquid'discharge from the cup or dipper-1nemher 106; theextension 36a being provided with an. outlet to which is connected thedischarge spout 3'?, as in the previously described construction.

The front Wall o?? the vessel 30, at a point within the extension 36',is provided an opening or slot for the passage ci the spout portion l0?of cup or dippersnemlser 106. in this construction, the spout 107 is soformed or bent that the cup or dippenniemher OG may be suspended fromthe front Wall or" receptacle 30E and therefore oscillate of thereceptacle 30a, as shown in Fig. Li. The spout-portion 107, is shownprovided with the semieiroular groove 108. :is more clearly shown in ig.The spout 107. like spout 42, is also provided with an upwardly preent/ed exten sion is provided with the elongated slot adapted to receivepin 46 on the lower i lever 4 7. which latter is operated through themanipulation or slide or plunger 56.

7lfhe neck' oi'the contaiiz or hoede 2Liis shown provided with anextension 4Q, like in Fig. l, in order to bring the outlet oii thehottie or container into horizontal plane beneath that ot the opening inthe front nwall of Vessel 30a throughI which spout 107 passes, so thatthe level of the liquid in Vessel 30u may act as an automatic seal forcontainer or bottle 24 and prevent the 50W therefrom except inquantities commensurate with the amount that is being; 'withdrawn fromvessel 30?, from time to time, through operation. of cup orflipper-member 106.

nthe or dipper-rnemher 10d, shown in CII charge or spout-'portion so asto control the point. ol' outlet from the cup or clipper-member. Theslot in the spout 10T, preferably terminatesl a short distance from thelower end of the spout so as to leave the imperforate portion 107n inthe lower part ot the dipper, as shown in Fig. 6. This permits theencircling band or regulatil'ig member 11.0 to be moved upward aconsiderable distance without uncovering the lower end of slot 109. Suchmovement will prevent the liquid in the lower part ot' the cup ordipper-nieinber 106 draining or discharging therefrom. lt

is evident from this construction that the quantity of liquid to bedispensed with each operation of the device may be controlled by thepositioning of encircling band or regulating member 110: for example. bv moving the band or member 110 upward on the spout-portion 107, withoutuncovering the lower end of the slot 109` a small quantity ot liquidwill be obtained with each operation of the device. 0n the other hand`a. greater quantity ot' liquid would be dispensed with each operation otthe cup or dipper-lneinber 106. when the member or band 110 is moved toitsI extreme upward position so as to uncover the lower part of Slot109, as thisl would allow the entire contents ot cup or dipper-meniber100 to be drained therefrom. f

The apparatus` as disclosed in Figs. tand l. is provided with thedrip-receiving funnel 111, mounted in the. same vertical plane asdischarge-spout 3T. so as to receive the drip therefrom and direct thewaste water into the waste vessel 25 located in the lower compartment ofthe tanlv' 20. The tunnel 111, as well as thev opening in the side wallofthe tank 20. through which the lower end of the funnel passes. is madeof a size sufficient to permit the passage ot' used or discarded cups.which will be directed into the drip and cup-receiving vessel 1n Fig. 5.we show a modification ol our invention adapted for privare use wherethe coin-controlled mechanism is not desired.

with the forwardly presented extension 36a, and the forward wall of theVessel 30b is adapted to be in close iliroximity with the wall of theouter or ice receptacle 10st, so as to permit the discharge or spout;107a of the cup or dipper-member 106a to extend througliiv a suitableopening in the wall of the outer vessel 104. The cup or clipper-member106, like.' cup or dipper-member 100, has a portion extending through anopening inthe front wall of Water-receiving vessel 301 and isoscillatingly mounted thereon. The opening in the vessel 101 is providedwith a' suitable shell 112, provided with a plunger 115, the lower endwhereof rests on a suitable boss formed on the discharge member or spout1071. It is evident from this construction that depression of plunger113 will cause the cup or clipper-member 106a to be tilted upward out ofthe position shown in Fig. 5 and force the outlet end of spout 107 1into a lower horizontal plane than the bottom of the cup orclipper-member 106, thereby allowing the liquid to be drained therefrom.The opening in the front wall of the liquid-receiving vessel 301 is in ahorizontal plane above that of the mouth or orifice of the invertedbottle or container 24, so that the liquid in vessel 30" willautomatically seal the container 2l and prevent flow from container orbottle 2l except when suticient liquid is taken from vessel 30b throughthe operation of the cup or dipper-member 106, whereby the level of theliquid would drop below the orifice of the bottle. 24. Theliquidreceiving vessel 30",` like the liquid-receiving vesselspreviously described, is provided with the upwardlvT presentedreceiving-por-- tion 105. adapted to extend through a suitable openingin the cover 114 ot' the outer vessel 104.

lVe have shown and described several evemplifieations of our inventaon,but it will be understood that the constructions illustrated maT bealtered incertain respects without` however, departing' fromA the spiritof our invention, and we. do not wish to be understocal therefore aslimiting ourselves to the exact construetiims shown and described.
